My invention. therefore consists essentialbination of various parts, and innumer'ous details and peculiarities of the same, suh

Sammy as will he hereinafter fully described and claimed.

In the accompanying my invention:

c it to he understood and plank' l in the form of a channel, having 1 raised parallel flanges 2, .2, at the edges.

Near each end or" the sandplank 1 are dependingyhangers 3, the i upperends 7 of which are hooked over tlieflanges 2 of the channel'plank' 1 said hangers 8-being se cured to the 'fianges 2 by means of boltsl Each hanger 3 .drops a certa in distance he 'lowgthe' sand plank 1 and this lower portion is provided with an angular or preferably right angled aperture, having a-iv'ertical part 10 and a horizontal part ll, the part 10 beingusually wider tlianthe part 11.

Supported in the right angled apertures ofthe" hangers 8 thatare" opposite to each other atea ch side of the truck, asf-shown in Figure 1, is a horizontal beam of angle iron,

which is passed horizontally through the f apertures in the hanger, and which can easilybe moved longitudinally. There are thus two of these beams, and each one has a horizontal'part 8 that passesthrough the hori- ,zontal part 110i the aperture in the hangers and a vertical part 8 1 that passes through the; vertical part 10. of the aperture in each hanger. i

It is of the that these anglebeams when once they have been properly positioned, should be immovably kept in such position until for any reason itbccomes necessary to take. them out or adjust them, and for the purpose of keeping them firmlylin such position I have devised specialmeans for doing this effectively. To this end the'horizontal member 8 of each bar is provided with a pair of-lateral notches 9,

one corresponding to each hanger with which F- the bar isu sed, so that when thebar 8 has been passed longitudinally through the horizontal slots '11 of the apertures in the hangers, this endwise movement will be adjusted so as to bring the notches 9 directly opposite ofthe hangers, as clearly shown Figure 52, and then the bar Wlll bejcaused to move horizontally, laterally, so that the member $8 1 slides laterally in the horizontal slot 11 of highest importance moreover the bar to be pressed against one side of the wider vertical slots 10 of the hanger apertures. This leaves a space between the member 8 and the opposite sides of slots 10, the slots 10 being wide enough for the purpose, and substantially wider than slots 11. Into the spaces thus left in slots 10 I insert a look ing block like that shown in Figure 7, which is a proper thickness for the purpose, and which is simply a square block, cut with short opposite slits to leave ears or parts 18, 18, which when the block is in place in a slot 10, as shown in Figures a and 5, may be bent at right angles to the face of block 12, and brought around against opposite faces of the hanger 3, so that as indicated in Figure 5 the parts 13, 13, form embracing lips with the hanger and lock the block 12 in the. slot 10 so that it cannot be shaken out. The angle bar is in this way closely and etfectively locked to the hangers and cannot be removed therefrom until the inturned ears 18 are straightened out again and the block 12 is taken out of the slot 10. In this way I utilized the great advantage of the safety bar below the brake beams in a railway truck by making it impossible for the safety bar to become dislodged from its normal attitude by wear or undue oscillation.

The bars and hangers are similarly applicable on each side of the truck as will be evident from the foregoing description, and the selected specimens or forms may be quickly modified without departing from my invention, the breadth of which is substantial and allows many changes.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is:

1. In an emergency brake beam support, the combination of a hanger having an aperture formed with a horizontal and vertical slot, and bar supported by said hanger, said bar having a horizontal notched member and a vertical member and adapted to be inserted in the apertured hanger, and a locking block also insertable into the apertured hanger alongside of the bar.

2. In a safety brake beam support, the combination with a truck frame and brake beam, of a channeled sand plank, rectangularly apertured hangers carried by the sand plank, notched bars of rectangular form which are passed through the apertures in the hangers, and locking blocks for insertion in the apertured hangers to lock the bars therein, said blocks having integral bendable lips to embrace the walls of the hangers.

In testimony whereof I hereunto my signature.
